I think Prism99 may have hit the nail on the head with your organization. I don't belong to a quilt guild but to a different type of 503c organization (fire company auxiliary). I also filed the paperwork (including articles of incorporation) with the IRS and appropriate state for my sister when she filed for 503c status for her wildlife rescue. Nowhere in (that) state or federal guidelines was what you are describing outlined that I recall.
For the organization to which I belong - our auxiliary is a sub organization of the primary volunteer fire company so our status is defacto to theirs. Almost all of the charitable activities, by default, happen at 'the place where we regularly meet' (firehouse) so that part is a non-issue for us. Our sub organization was formed specifically for the intent of fund raising at the time (80+ years ago). And while 99% of those activities happen at the firehouse, there are other community-type events where we will do fund-raising activities as well.
